Hi @TanvirRafi, sorry to hear about this.

Do you see the lines when you boot up the device as well or is only when Android is started and you have used your screen lock to unlock the device?

Just to make sure that nothing is enabled in the developer options, go to Settings > System > Advanced > Developer options > turn this off at the top. Is there any change when you do this?

Let me know if that helps!

Yes my developer option is turn off.

And i see the lines when display on for 2 or 3 minutes then the lines go and again come after few seconds. It is continuously happened when disply on for long time.

Hi again and thank you for the information.

You could try booting the device in safe mode and see if it occurs when downloaded applications aren't loaded, but to be honest, it sounds more like it's related to hardware and not software.

If there is no change in safe mode, perform a software repair using Xperia Companion but remember to backup your data since the repair will delete everything from the internal storage.
